## Homework Statement

I have to answer questions 1 - estimate the size (in volts) of the DC signal from CH1

and 2-estimate the peak-to-peak voltage AC signal of CH2, then find it's period and frequency

And then I'm supposed to 'briefly describe a simple example in wich oscillations or waves with two or more frequencies are combined"

I don't know how to work out 1 and 2 from the diagram, I don't understand the scaling of the side to work out where each of them is.

And with the briefly describe part, is that just refering to how when you put two waves together with different frequencies, the amplitudes of each of them are added together to form a new wave-like shape?
